Oaks across California's Summer-Gold Hills

Oaks across California's Summer-Gold Hills is an original illustration set in Central California Coast Ranges, United States. It lies in mid-latitudes, where the climate is mediterranean — hot dry summers, wet winters.

Broad rolling hills are covered in dry golden grass with widely scattered dark evergreen oaks. Denser chaparral fills cooler shaded folds, a few cattle graze beneath open crowns, and a low bank of pale marine fog presses against distant coastal ridges.

Why are evergreen oaks widely spaced across golden hills while fog waits near the coast?

California's wet winters and rainless summers favor annual grasses that cure gold and drought-tolerant oaks with deep roots and open canopies. Chaparral thickens where slope exposure and soil moisture differ, while Pacific fog can cool the outer ranges without bringing dependable summer rain inland. The repeated oak spacing, Mediterranean summer dryness, and coastal fog boundary make this landscape distinctly Californian.
